Re: [aspectj-users] Invoking proceed() from an inner class

[Archie Cobbs <archie@xxxxxxxxxxxx>]

Thank you both for the very helpful suggestions.

It appears that the following simple pattern works, and there is no need to use ProceedingJoinPoint:

    Object around(final Object obj) : somePointCut(obj) {

      // Prepare for execution
      final Callable<Object> action = "" Callable<Object>() {
          @Override
          public Object call() throws Exception {
              return proceed(obj);

          }
      };

      // Do whatever...
  }

Does this look OK? I didn't realize that the AJC compiler would properly handle proceed() inside a nested class, but it appears that it does.

I'm using AspectJ 1.7.2.

Thanks,
-Archie

Is it possible to invoke proceed() in an aspect from an inner class?

I have a need to pass off the execution of an advised method to another method that is going to invoke it as a Callable. This will all be done synchronously.

A simplified version of what I'm trying to do would be:

  public aspect MyAspect {

    Object around(final Object obj) : somePointcut(obj) {
        Callable<Object> c = new Callable<Object>() {
            @Override
            public void call() throws Exception {
                return MyAspect.this.proceed(obj);
            }
        });
        ...
        return c.call();
    }

In the real version, c gets passed off to another method that invokes and returns c.call().

If that's not possible, is there some other way to "wrap" the advised method invocation in a Callable?

Thanks,
